To all whom it may concern. 3 M

Be it known that I, JAMES A. Ginsu, 'a citizen of the United States, andresident of Chicago, county of Cook, and State of Illinois, haveinvented certain new anduseful Improvements 1n Window-Stops, of whlchthe following is a specification, andwhich are illustrated in theaccompanying ings, forming a part thereof.

The invention relates to stops for windows; its object being to providea construction in which the stop is moved toward the sash by the weightthereof, when engaged by alocking bolt, thereby forcing the sash againstthe opposing stop and insuring a tight'joint.

draw- The invention consists in a structure such A window casing isrepresented at 1.0, and a sash fitted thereto at 11, both being ofordinary construction. The sash is shown as provided with a pair oflatches 12, 13, of any desired form, comprising a reciprocating bolt 14.The outer stop 15, against which the sash 11 bears, may be of anypreferred form, preferably stationary, and

there is shown a common rectangular part- 1ng strip for this purpose.

The improved stop is applied to the inner face of the sash and comprisesa plate 16, secured to the inner face of the stile member of the windowcasing. As shown, this plate is provided with a pair ofparallellongitudinal flanges 17, 18, which provide a runway for a windowcurtain. This feature, however, forms no part of the present invention.To the face of the plate 16 there is applied a movable stop member 19,having the general form of a channel bar, the chain nel facing towardthe plate 16 and the inner side face of-the bar being adapted to bearagainst the face of the sash. This bar 19 is vertically and laterallymovable, and is held in place by lugs 20 (three being shown),

- whichareffixedto the plate., 16 and project into slots 21 formed inthe inner side or flange: of the bar 19. Cams are provided for. movingthe bar-19- laterally as it'is moved vertically. For this purpose thereis shown a plurality of plates 22, 23 and 24,.as many being employed asmay be deemed advisable. Each of these plates is provided near its lowerend with a beveled face 25, with its edge remote from the sash,theinclination of this face being upwardly away fromthe sash. Eachofthese. plates is provided near its'upper end, and onits edge adjacentthe sash,'with a similarly inclined'fa'ce 26.

Gam'surfaces' 27, 28,"aref provided on the inner faces oftheside'fianges of the bar 19,

both being inclined upwardly away from ;the sash and so positioned as tocooperate with the beveled faces 25,26, of the plates 22,23, 24. Thevertical movement'of the bar 19 is determined by the length of the slots21. When the barisinits upper position, as shown in Fig. 4:, it iscammed backwardly away from the sash by the cooperative action of theinclines 25,27. I When it i'slowered it is cammed toward" the sash bythe cooperative action of the inclines 26, 28.

If desired a spring 29 may be provided for holding the bar 19 in itsupper position.

Apertures 30, 31,32, 33, as many as may be deemed advisable, are formedin the web portion of the bar 19 for receiving the latch bolt 14:. Whenthe bolt enters one of these apertures the'weight of the sash will drawthe bar 19 downwardly, and the lateral movement of this bar will forcethe sash snugly against the opposing stop 15. A lug 34 is preferablyformed on the face of the web portion of the bar 19, at the lower endof-the bottom bolt-receiving aperture 30, insuring the downward movementof the bar and bringing the aperture 30 in alinement with the bolt whenthe sash is in its lowest position. For the purpose of reinforcement ofthe bottom walls of the apertures31, 32 and 33, fix'ed'supports 35, 36and 37 are preferably. attached to the plate 16, and so posibar 19preventing the sash from descending rapidly when the latching bolts arewithdrawn. 7

' It will be understood that the improved stop is preferably applied atboth sides of the window casing. A stop 38 is formed on the bar 19 inposition to be engaged by the upper face of the locking bolt when thelatter enters and passes through theaperture 80,firmly holding the sashin closed position. Various changes in details of construction may bemade without departing from the scope of the invention. The constructionshown and described is durable and operates satisfactorily, both withand without the spring. s

The device tends to firmly hold the sash against the opposing or fixedstop throughout its entire vertical length, insuring complete exclusionof the weather and effec tively preventing settling of the sash when inany of its positions. 7

I claim as my invention- 7 1. In a window stop, in'combination, a plateadapted for attachment to the side member of a window casing, a seriesof vertically arranged cam elements each having oblique faces on theirsides adjacent the runway for a sash, such faces being inclineddownwardly toward such runway and oblique faces on their opposite sidesinclined upwardly and away from such runway, a channel bar inclosingsuch cams and having bearings engaging both sets of such oblique camfaces, such bar being apertured to receive a sash bolt.

2. In a Window stop, in combinatioma plate adapted for attachment to theside member of a window casing, a series of vertically arranged camelements each having oblique faces on their sides adj accnt the runwayfor a sash inclined downwardly toward such runway, and oblique faces ontheir opposite sides inclined upwardly and away from suchrunway, achannel bar inclosing such cams and having bearings engaging both setsof such oblique cam faces, such bar being apertured to receive a sashbolt, and having an outstanding bolt engaging lug at the lower margin ofthe lowest bolt receiving aperture.

8. In a window stop, in combination, a stationary member, a slidingmember carried thereby and having a bolt aperture, a lug on the slidingmember at the bottom of the bolt aperture, and a bolt-engaging lug onthe stationary member at the upper end of the bolt aperture when thesliding member is at its lower position.

4. In a window'stop in combination, a stationary member, a verticallyand laterally movable member mounted thereon, such two members beingengageable by a sash bolt when the sash associated with the stop is inits lowest position. v

5, In a window stop, in combination, a stationary member, and avertically and laterally movable member carried thereby, the-movablemember being adapted to be moved downwardly and toward the sashassociated with the stop by the closing of the sash, and the stationarymember being engageable by a sash bolt when the sash is in its closedposition.
